A new study from the University of Waterloo has found that in some ways, the older you get the worse your decision making becomes.

The study established that younger children seem to make slightly better decisions than older children. The older children get, the more they tend to ignore some of the information available to them when making judgements, which though efficient can also lead to mistakes.

PHOENIX, Ariz. -- July 18, 2018 -- DNA methylation is a molecular process that helps enable our bodies to repair themselves, fight infection, get rid of environmental toxins, and even to think. But sometimes this process goes awry.

A team of scientists led by the Translational Genomics Research Institute (TGen), an affiliate of City of Hope, has identified how DNA methylation is associated with a condition known as non-alcoholic fatty liver disease (NAFLD), which can lead to liver cirrhosis and death, and is one of the leading indicators for liver transplants.

Even when people have well-connected social networks beyond their home cities and across state lines, they are still most frequently interacting with people who are very geographically near.

That is one of the major outcomes of an expansive, 16-month study of more than 51 million geo-tagged tweets generated by more than 1.7 million Twitter users across the U.S. The study was funded, in part, by the National Science Foundation.

NEW YORK...July 18, 2018 - A new highly maneuverable search and rescue robot that can creep, crawl and climb over rough terrain and through tight spaces has been developed by Ben-Gurion University of the Negev (BGU) researchers.

Having an early supper or leaving an interval of at least two hours before going to bed are both associated with a lower risk of breast and prostate cancer. Specifically, people who take their evening meal before 9 pm or wait at least two hours before going to sleep have an approximate 20% lower risk of those types of cancer compared to people who have supper after 10pm or those who eat and go to bed very close afterwards, respectively.

New evidence published today shows there is little or no effect of omega 3 supplements on our risk of experiencing heart disease, stroke or death.

Goofy, yellow and crooked: British smiles have sometimes had a less-than-flattering international image, but a new study has put tartar from our infamously bad teeth to good use.

Researchers analysing the teeth of Britons from the Iron Age to the modern day have unlocked the potential for using proteins in tooth tartar to reveal what our ancestors ate.

Dental plaque accumulates on the surface of teeth during life and is mineralised by components of saliva to form tartar or "dental calculus", entombing proteins from the food we eat in the process.

Anyone lost in a desert hallucinating mirages knows that extreme dehydration discombobulates the mind. But just two hours of vigorous yard work in the summer sun without drinking fluids could be enough to blunt concentration, according to a new study.

Engineers at the University of California San Diego have shed new light on a scientific mystery regarding the atomic-level mechanism of the sulfur embrittlement of nickel, a classic problem that has puzzled the scientific community for nearly a century. The discovery also enriches fundamental understanding of general grain boundaries that often control the mechanical and physical properties of polycrystalline materials.
